Assistant: Fix a name of a bookmarks folder

The folder named "Toolbar Menu" is meant to contain bookmarks which
are displayed on the bookmarks toolbar rather than in some menu.
So the name "Bookmarks Toolbar" is more appropriate, besides it is
consistent with Firefox and is similar to Chromium's "Bookmarks bar".
